I note the existence of at least three levels of decoder. The mini series which seem to be rated at about 0.5 amps, the standard series at about 1.5 amps & larger decoders for the big scales.

I would interpret the above a meaning that mini decoders were for "N" & that standard decoders were for "OO" yet I understand many users have mini decoders in their "OO" locomotives.

I am capable of finding the stalled current of my motors but I do wonder if this is what others use to determine the capacity of decoder required for a particular loco.

Am I going to get problems if I put mini series decoders in commercial "OO" locos as they are obviously easier to fit in some cases?
